Top tip! Old buildings usually become damp when barriers to moisture are added. New buildings become damp when such barriers fail.
☂️Modern houses are a bit like a raincoat. They're typically designed to keep moisture out in the first place -- with cavity walls and floors that use impermeable materials like cement.
When these barriers fail, dampness tends to creep in.
🌬️But in contrast, old buildings are much more like an overcoat. They're designed to be breathable -- it's how they stay dry. This involves using 'moisture open’ materials, like lime, that encourage moisture to evaporate quickly and easily, rather than trying to restrain it.
